Question 4. Select the statement that best describes the PM wave.a. Carrier phase angle changes represent the PM modulated signal, however, unlike FM and AM modulatedcarriers, it is not always easy to see these phase changes in the plot.b. The FM signal accurately represents the message.c. Although PM and FM techniques are classified as angular modulation techniques, they cannot be usedinterchangeably (i.e., modulated with FM and demodulated with PM, and visa versa).d. All statements are correct.

Design an encoding matrix with diodes and resistors to display a decimal number to on the seven-segment display. You have 10 switches (WO-W9) with one terminal connected to Vec. For decimal number 0, switch 0 (S0) is closed, for decimal number 1, switch 1 (S1) is closed etc. (Switches are on the vertical axis, S0 on top and the outputs are taken on the horizontal axis (Y0-Y6), with “a" on the left and "g" on the right. Note that (Y0-Y6) outputs are used as inputs to seven-segment display. Since these outputs cannot drive the seven segment display LEDS you may need additional bipolar transistors and resistors. The supply voltage is 5V and each LED needs a current of 20mA. Note that this is a design problem and the design is not unique. Do your best! f a a e
